Trends in contemporary Italian narrative 1980-2007

The ‘new Italian narrative’ that began to be spoken about in the 1980s was not associated with a single writer or movement but with an eclectic and varied production. The eight essays that make up this volume set out to give a flavour of the breadth and range of recent trends and developments. The collection opens with two essays on crime fiction. In the first, Luca Somigli examines novels dealing with topical issues or recent history and which reveal a strong indigenous and regional tradition, while in the second, Nicoletta McGowan discusses the particular case of a noir by Claudia Salvatori. They are followed by essays on two of Italy’s best-known contemporary writers: Marina Spunta’s essay explores the representation of space, place and landscape in the work of Gianni Celati and photographer Luigi Ghirri, while Darrell O’Connell analyses the fiction of Vincenzo Consolo, and his struggle to find a means of representing an ethical stance within fiction

Nanoscale electrical conductivity imaging using a nitrogen-vacancy center in diamond

The electrical conductivity of a material can feature subtle, nontrivial, and spatially-varying signatures with critical insight into the material's underlying physics. Here we demonstrate a conductivity imaging technique based on the atom-sized nitrogen-vacancy (NV) defect in diamond that offers local, quantitative, and noninvasive conductivity imaging with nanoscale spatial resolution. We monitor the spin relaxation rate of a single NV center in a scanning probe geometry to quantitatively image the magnetic fluctuations produced by thermal electron motion in nanopatterned metallic conductors. We achieve 40-nm scale spatial resolution of the conductivity and realize a 25-fold increase in imaging speed by implementing spin-to-charge conversion readout of a shallow NV center. NV-based conductivity imaging can probe condensed-matter systems in a new regime, and as a model example, we project readily achievable imaging of nanoscale phase separation in complex oxides.Comment: Supplementary information at en

Hybrid gain-flattened and reduced power excursion scheme for distributed Raman amplification

We propose and evaluate through extensive numerical modelling a novel distributed hybrid amplification scheme combining first and second-order Raman pumping which gives reduced signal power excursion over a wide spatial-spectral range of 60 km × 80 nm in C + L-bands
